feat: create new sPoNgEcAsE and modify raNDOmcASe to be random (@Justiniscoding)

[Justiniscoding]

Description

The old rAnDoMcAsE mode was not actually random and more accurately reflected sponge case. I modified the old rAnDoMcAsE mode and turned it into raNDOmcASe, where it calls Math.random() for every letter and bases the capitalization of of it. The old code from rAnDoMcAsE was moved to a separate sPoNgEcAsE funbox mode.

Changes

• rAnDoMcAsE becomes raNDOmcASe and has a 50% chance to capitalize every letter.
• sPoNgEcAsE is added as a funbox mode and contains the old functionality of rAnDoMcAsE
• "i KINda LikE HoW inEFFICIeNt QwErtY Is." challenge is updated to use the updated raNDOmcASe mode as well as a new title that is in proper random case.
